Hardware, Embedded Systems "Samsung Electronics and Microsoft will next month show off the ready-to-market version of a hybrid hard drive which can greatly reduce boot-up time of laptops and desktop PCs. The HHD is the convergence of a flash memory chip and a conventional platter-type magnetic disk drive. To save the time and energy spent spinning a metal disk drive it is designed to use static flash memory when starting a PC."

I don't think you guys get a lot of this. When I first saw it, I was like holy cow! This is a BIG ONE. The only thing that's bigger is Flash drives.

Reading the press releases, the 1 Gigabit OpenNAND acts as a big buffer. My guess is that it's one drive.

First off, you need to get out of the desktop is the only use for PCs mode.
--Laptop users power cycle fairly often. There may be a suspend mode, but most just power down.
--It really bumps up Vista as a Consumer Electronics OS. More so than XP Media Center, OS X, BSD, or any Linux. I'm geussing this is the primary thrust.

You save quite a bit more than "1 or 2 seconds" on boot. To go from a complete cycle off to the login screen can be well over 30 seconds, esp if the user has plenty of boot-time processes.

While operational uses will not be affected as much, since predictive technologies aren't that fantastic yet, but it will reduce hard drive spinning. While currently hard drives continue spinning unless told otherwise in power save dialogs, this drive will be spun down.

I'm sure things can be optimized, i.e. if you're playing a game, the game and maps can be loaded here since it's unlikely you'll be doing anything else. In gaming, map loads are biggies. I just don't think it will be an overall performance boost in day-to-day applications.

If the drive isn't spinning as much, it reduces operating temperature and prolongs drive life. It uses less power since the drive is spun down more often and thereby prolongs battery life - or at least offsets some of the power needed to run Vista's graphics.

After I read it, I realized that this was a big leap and so I read other press releases. This is a Microsoft Technology. You can't say "let MS not be a part of it." Some press releases refer to it as "Microsoft's Hybrid Hard Drive Technology" that uses Samsung's OpenNAND. They ARE it and Samsung is a part of it. This means that if they want, they can not offer it openly. It's theirs, they paid for it and developed it. They don't have to share this time. It uses additional ATA commands they developed to improve efficiencies. If Red Hat, Novell, IBM or Apple want to develop this technology, they can pay for its development.

With that said, I'm sure Apple will leapfrog them to Flash disks. Various OSS developers will reverse engineer it and it'll make it to the OSS community. As far as what I read, it appears other unnamed HDD OEMs are licensed to produce and volumes start later this year.

But in performance, having near-instant on would be a big victory.

Google Samsung Hybrid Hard Disk (or Drive) for more info.
